Men's basketball at a glance | No. 13 Kentucky at Arkansas

Kentucky freshman Julius Randle goes hit to clear Vanderbilt center Damian Jones at Memorial Gymnasium in Nashville, Tenn., on Satuday. Randle was plagued by leg cramps in the second half for the third game this season.

? Kentucky's star freshman struggled with leg cramps for the third time - publicly - this season Saturday at Vanderbilt. He also had to leave the postgame press conference after a loss to Michigan State and barely played the second half against Louisville because of cramps. So what gives? "Well, first of all, I really believe he's got to get to cramping in practice," coach John Calipari said. "He's got to go that hard in practice. He's not cramping in practice, so that leads me to believe he's got to step on the gas there." Calipari, who can't recall ever having a player deal with this so often, said the staff has also looked at Randle's diet and done blood testing. "But I believe when you go at the pace he goes - because he goes really, extremely hard - your body says, 'Hey, man, slow down,' " Calipari said. "We've probably got to get him a quicker rotation so that he's in and out instead of staying on the floor seven, eight, nine minutes, 10 minutes. Let him go three or four minutes, come out, go back in, and play a little bit different rotation."

? Calipari has praised Poythress' spike in energy the last few weeks. Poythress has become a spark off the bench for Kentucky, averaging 8.2 points, 5.2 rebounds and a block over the last five games. But his shooting, in every category, is down this season from last - 58.1 percent to 50 percent in field goals, 42.4 percent to 33.3 percent on 3-pointers, and 68.9 percent to 48 percent on free throws. So is that due, in part, to the focus in practice on his effort over form? "Possibly," Calipari said, "but if you understand me as a coach, that stuff will all come in line. The other is, until they do that (play hard), the rest of the stuff really doesn't matter. If you're not going to compete at a high level, if you're not going to have your mind and your body in the physical and mental shape it needs to be in to compete, I don't care if you make shots or not, or make free throws. It really doesn't matter. You're not going to win. You're not going be a winning player. He's now put himself in a position to be a winning player."
